[imp] https redirect to port 80 + Apache Segfaults

[Gonzalo Servat]

Hi All,

Sorry for re-posting but I didn't get any responses, which is rather 
strange for this list :)

I've got a couple of problems. Problem 1 as follows:

On every other login attempt to IMP, IE just hangs after you click on 
"Login" and in Opera it displays "Access to this port is denied for 
security reasons". Fortunately, Opera gives me a hint as to where it's 
trying to go for the error to come up. On the title of the error page 
window you can see the URL https://www.domain.com:80/webmail/mailbox[...]
Notice how it's trying to redirect to https (and on port 80) ??

If you click OK and try to login again it usually works and redirects to 
the right place (http://www.domain.com/webmail/mailbox[...]). Any ideas??

Running Apache 1.3.27, PHP 4.3.1, Horde 2.2.3 and IMP 3.2.1

The only difference between my setup and a standard IMP/Horde install is 
the following lines in httpd.conf:

Alias /webmail "/home/httpd/vhosts/webmail/horde/imp/"
Alias /horde "/home/httpd/vhosts/webmail/horde/"

I also added the right <Location ...> directives and modified the webroot 
in registry.php for Horde to match the above. Probably irrelevant, but just 
thought it's worth telling.

.... and as for Problem 2:

I seem to be getting more and more frequent segmentation faults in Apache 
and they usually come up when using IMP. It will come up with the infamous 
"Cannot find page or server" in IE and in the Apache logs:

[date] [notice] child pid xxxxx exit signal Segmentation fault (11)

How do I troubleshoot these segfaults further?

Thanks in advance for any help.

Kind regards,
Gonzalo
